摘　　要：利用某高校宿舍楼疏散演习的录像资料,得到了楼梯间出口的通行系数、下楼速度及下楼速度与人员密度的关系,并与其他学者的结论进行了对比分析。为研究疏散距离对疏散速度的影响,在某超高层建筑内进行了疏散试验,得出了下楼速度折减系数与疏散距离的关系式。研究结果表明,首层楼梯间出口的通行系数是影响疏散效率的主要参数;随着疏散距离的增大,下楼速度逐渐下降。Making use of the evacuation drill video in a university dormitory building, this paper got the outflow rate at the stair- case, the speed of going downstairs, and the relationship be- tween downstairs speed and occupant density, meanwhile, ana- lyzed and compared the result with other researchers ＇ conclu- sions. In order to study the influence on evacuation speed by e- vacuation distance, it undertook the evacuation test in a super high-rise building, and got the equation of going downstairs re- duction coefficient and evacuation distance. Results showed that the outflow rate at the first floor staircase is the key factor of e- vacuation efficiency~ speed of going down decreases with the e- vacuation distance increases.
